Ambergris Caye, pronounced "am-BER-gris", is the largest island of Belize located northeast of the country in the Caribbean Sea. Though administered as part of the Belize District, the closest point on the mainland is part of the Corozal District. The Caye (pronounced as "key", meaning an island, derived from the Spanish language "cayo") is about 25 miles long from north to south, and about one mile wide. It was named after large lumps of ambergris which washed ashore here.
